Might I suggest putting a sponge on the outlet? It makes the best bed so long as you keep the water level up. I have two of those tanks and both my bettas use them. I have extras and can mail you one if you like or, they're available on Amazon.
I bought the pre filters off Amazon, they come in a 3 pack. I was going to offer to mail you a spare but judging by your comment history it looks like you're in Australia? I'm in the states and will only mail to US address...they're cheap though!
You can probably find them pretty easily. I ordered this pack on amazon which comes with three since I had more than one tank, but I'm sure anything similar to that will work fine. It's just basically a little cylinder shapes sponge sleeve that you stick over the end that sucks up the water.
This is what it is. Just slides right over that and protects your fist from swimming to close and getting his fins sucked in. It doesn’t matter if it’s not the same brand as your filter either.
Zanyzap Pre-Filter Sponge 3 Pack for Fluval Edge Aquarium [link]
Thanks for the reply. Good to hear that it's not necessarily the shrimp.
The only objects he could have scraped himself on are some pieces of cuttle bone that I've got in there for the snail, but the discoloration has been a steady enough spread that I don't think it's an injury. Last week it started on his lips, the bleaching you can see under his dorsal fin is from the past 72hrs and the "stripe" on his side just appeared today.
There's no hardscape and the sponge I've got installed to calm down the flow from the return valve doesn't seem like it could hurt him; otherwise the tank is just stuffed full of chain sword and water lettuce. No decorations.
I don't have a spare tank to use for a quarantine, but from what I understand Paraguard is safe for snails/shrimp despite the "not recommended for inverts" warning on the label. None of the inverts seem disturbed at all after 3 days of treatment.
I can't say to what degree she's hurt, but she's likely injuries in some way. Doesn't mean it'll be fatal, but at minimum she'll need time. Unless you have other fish in there with her, you could likely unplug the filter for a few days to ease the stress on her. In the meantime, I'd attach a foam media intake sponge to your filter as this will reduce the risk of future incidents. I have shrimp and fish and have no problems with them and the filter using these. In fact, the shrimp feed off of them!

Don't worry, they're pretty much universal, so even though they state they're for fluval I use them on a completely different brand with no issue. I get them longer, which means they're deeper and they stay on without any help but the filter's own suction. Hang in there, I'm sure she be fine. You might want to also get some stress additive that might have something for healing too.
Well, not to be a shill, because I really don't wanna be... but lately I've been buying my prefilters from these guys.
Literally had a CPD fry and countless shrimp fry not get killed from them so I'd guess that's a pretty good endorsement lol.
By the way, these work well on the intake for mine, they are a little finer than some of the others so will pickup more fine particulates, ever once in a while I will swap one out and clean the old one. Makes me have to clean the actual filter sponge much less often.
I cut off the bottom part of the 2nd intake tube that came with it (the pointy part), and used it to extend the tube. With an intake sponge [link], it is about 1cm off of my substrate.
Seconding sponges! My Eheim's spray bar is a bit too forceful as well, and I have covered it with these Fluval cylinder sponges. I used a knife to poke a hole in the bottom of the sponge so I could easily slide it onto the bar. Of course, any shape of sponge can be cut and molded and tied where necessary. I just went for the fool proof option (alas, I am only a fool).
"Especially by my filter"
This is likely very easy to fix for your filter in a 10 gallon. Simply slide that sponge over your intake valve and it prevents the babies from getting sucked up. It also prevents the grownups from having their fins sucked up and ripped. Lastly, it acts as another layer of filtering for your tank!
Even at less than an inch, it can create a downflow too strong for a fish like a Betta with such large fins (as you've clearly witnessed). Think about a sail boat... even a soft wind will billow the sails. That's exactly what their fins are.
While the filter intake wouldn't be a problem for other fish with smaller fins, that might create an issue with a Betta. I'm sure he'll be fine for today while you go to work, though. For later, you can simply increase the size of the sponge on the intake to slow down the flow. I bought a bunch of these a while ago for various purposes (great for scrubbing glass on small aquariums!), and they're dense enough to slow water flow pretty significantly.
Also, I have to say - kudos to you for being so concerned and attentive to a fish you received as a gift. Most people (sadly) would throw him in a vase on a window sill and forget about him until he started smelling. I really admire your desire to learn as much as you can so you can take good care of him.
Yeah with Fluvals, for bettas, you either need to poke a few holes in the pump's tube or buy some foam to block the intake or output. I bought these sponges and put them on my output nozzle in my specs and they've been perfect for my bettas.
I also wouldn't put that frog in there, it's too much bioload. I also bet that he's trying to sell you an African Dwarf Frog. A 3 gallon tank would be great for 3 ADFs, but your Betta is using all of that bioload. At best I'd put in a few ghost shrimp. They're cheap, so if your betta eats them it's no real loss, and if he doesn't he'll have something to entertain him. I have several ghost shrimp in my tanks with friendly Bettas.
It's called a pre filter sponge. Here's the fluval one [link]
If you're going to stay with the live plants the internal filter is better. Because you don't want to out gas any co2 your fish and plants have been building up. Or if you want you can get a mini canister filter, they're great. You can do all sorts of neat stuff with them like adding in in-line heaters and co2 reactors. Plus they filter better.
Are you taking the impeller completely out of the housing to give it a good scrub?
It sounds like stuff is definitely getting lodged in there, so the easiest way to prevent the issue is prevent stuff from getting in. A prefilter sponge is the way to go if the problem continues.
Sponge filters are great, I even have a couple for some of my tanks, but you could get a pre-filter sponge for your current filter to make it work. The sponge lessens the flow and keeps the betta's fins from getting ripped up by the intake tube. You won't need to buy another filter or air pump and the pre-filter sponges have the best of both worlds; mechanical filtration and the sponge for beneficial bacteria growth.
A sponge can definitely help. I used one for the intake on my canister filter and it does the trick.

This is what I used specifically; it fit the tube well. I'm not sure if the intake tube is different depending on which AquaClear you have but you can check your LFS to see if they have something that would fit snug; worst case you could tie or glue it down.
Where do you get \ what do you call the little foam bit you have on the uptake for your filter?
Edit: Nevermind. I managed to find them this time around: [link]
Probably. He looks fine for now, but you might want to consider a cover for your filter intake. Whether you buy one or make one, sponge pre-filters are good for a number of reasons. They slow the flow so a fish doesn't get stuck or have his fins ripped up. They also provide a good place for beneficial bacteria to grow.
How much do you feed him? The left over food stuck to the filter intake is a likely sign that he's getting over-fed. Most bettas gobble up an appropriate amount of food before it has a chance to get sucked into the filter.
Be mindful of sand getting into your filter and messing up the impeller magnet. Had it happen to me before when I had sand.
One thing you could do is buy this and put it over the intake:
Petsmart sells them for like $2.
Consider getting a filter intake sponge cover?

My betta and corydoras love to rest on it. Weirdos.
No problem! I've bought a couple brands, but here's one of them [link]
i've used these and never had any problems.
you'll have to clean them off every couple days, but thats not a huge deal. you could just rotate them out.
These will help.. Sorry about the link. I'm on mobile. I have this on mine.. Just rinse them when you do a water change:
You definitely need a sponge for your filter intake, I got these here [link]
Here you go:
I think there is a larger pack too. And it doesn't just fit fluval. Mine is an Aqueon.
Hrm, something is missing.
Here's the link at least: [link]
The pre-filter looks like this and should fit over most intake tubes. It was purchased from Amazon as a three pack labeled as sponges. I don't have anything special going on with the cartridge or internal filter media for that tank. The sponge filter is just a basic sponge filter.
Im not sure why your snail is going there, perhaps there is a lack of food in your aquarium? Anyways, try these.
